You can safely unload it by renaming the .sys to .old in its respected directory, and then restarting.
If the cleared CMOS does not help, and your BIOS is already up to date, this is very likely a faulty processor. There is virtually no way of me telling you if it's a motherboard vs a processor problem, due to there being no diagnostics for either. FWIW, L2 Cache errors generally imply a standalone processor failure, and not a board problem. Also, this does not look like a PSU problem at this time whatsoever. We'd have different symptoms/errors.
